The World of Tanks beta for Xbox 360 is starting this weekend, Wargaming has announced. The test is pretty limited for now, only open for set times all three days this weekend, but Wargaming assures eager tankers that this is the beginning of several more phases to come.
According to the announcement, the beta will run between 3 PM and 9 PM PT each night this weekend (June 28-30). Those are concentrated play sessions to stress test the servers, and they request you hit up the forum with any feedback or bugs.
The invitations for this phase went out last night and today, so if you didn't get one, you probably aren't in the first wave. However, it promises it will be open to more and more players each weekend, so it sounds like they'll be starting new tests with some regularity. Beta sign-ups are still open.
